This chart displays the daily average temperature (blue line) and dew point (red line) from 1981 to 2010. The shaded regions show the typical range (\(\text{10}^{\text{th}}\) to \(\text{90}^{\text{th}}\) percentile) for each measurement. The overlapping area between the blue (temperature) and red (dew point) ranges indicates the days and temperatures where the air is expected to be fully saturated with moisture (100% relative humidity)
This graph shows negative relationship between dew point and wind speed broken down by time of day.
These bar graphs show the wind direction frequency for the four different seasons. The wind direction means the direction that the wind is coming from. Wherever it is coming from it is blowing in the opposite direction. So SW means that the wind is blowing NE. Notice with the bar charts that in the winter wind is coming almost entirely from the west (blowing east). In the Summer there is more of a mix of directions, but the wind is almost entirely coming from the southwest. Fall is a balance between southwest and western winds which makes sense as a transition between Summer and Winter. Spring is the most notable of the seasons because it is the only one with a significant amount of northwestern winds.
This chart measures the dew point difference by season. Dew point difference is used to gauge relative humidity. The higher the difference between dew point and temperature, the less relative humidity there is. This means that relative humidity is the highest in the winter and the lowest in the Spring. This is notable as Winter and Spring represent the extremes, but the seasons are right next to each other.
